SM-70
WIRELESS STEREO MONITOR SYSTEMS

Multiple frequencies are available.
16 transmitters can operate simultaneity in the same channel and do not interfere.
No limit of the receivers, infinite receivers can operate in the same band.
Optional stereo and mono modes.
Field strength and noise measure, double squelch quantum
adjustment control, efficiently improve the
preventing of noise interference in the environment.
Professional dynamic compressing expand and dynamic limited
technology ,the system can endure the super dynamic
iutput avoidingdistortion.
